EPO (Emergency Power Off) Function

These units are equipped with terminals for receiving an EPO (Emergency Power Off)

"closed contact" switch command from two locations:

(1) a remote location and (2) from a

front panel mounted EPO switch. This safety feature enables quick shutdown of the UPS

AC output and battery circuits.

Usually the EPO switch is installed in a central location that

is easily accessible to personnel concerned with the operation of the UPS and the

equipment connected to it.

The EPO function is initiated by pressing the switch to the

closed "shutdown" position.

The effect of using the EPO switch is the same whether the

UPS is in the AC Input Mode, Battery Backup Mode, or the Bypass Mode. See

'EMERGENCY OFF' screen. The following figure shows the UPS condition after

application of the EPO switch.

Use the Start-up Procedure for restarting the unit.
